*  Purpose
*  =======
*
*  SDRVLS tests the least squares driver routines SGELS, SGELSS, SGELSX,
*  SGELSY and SGELSD.
*
*  Arguments
*  =========
*
*  DOTYPE  (input) LOGICAL array, dimension (NTYPES)
*          The matrix types to be used for testing.  Matrices of type j
*          (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) =
*          .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used.
*          The matrix of type j is generated as follows:
*          j=1: A = U*D*V where U and V are random orthogonal matrices
*               and D has random entries (> 0.1) taken from a uniform 
*               distribution (0,1). A is full rank.
*          j=2: The same of 1, but A is scaled up.
*          j=3: The same of 1, but A is scaled down.
*          j=4: A = U*D*V where U and V are random orthogonal matrices
*               and D has 3*min(M,N)/4 random entries (> 0.1) taken
*               from a uniform distribution (0,1) and the remaining
*               entries set to 0. A is rank-deficient. 
*          j=5: The same of 4, but A is scaled up.
*          j=6: The same of 5, but A is scaled down.
*
*  NM      (input) INTEGER
*          The number of values of M contained in the vector MVAL.
*
*  MVAL    (input) INTEGER array, dimension (NM)
*          The values of the matrix row dimension M.
*
*  NN      (input) INTEGER
*          The number of values of N contained in the vector NVAL.
*
*  NVAL    (input) INTEGER array, dimension (NN)
*          The values of the matrix column dimension N.
*
*  NNS     (input) INTEGER
*          The number of values of NRHS contained in the vector NSVAL.
*
*  NSVAL   (input) INTEGER array, dimension (NNS)
*          The values of the number of right hand sides NRHS.
*
*  NNB     (input) INTEGER
*          The number of values of NB and NX contained in the
*          vectors NBVAL and NXVAL.  The blocking parameters are used
*          in pairs (NB,NX).
*
*  NBVAL   (input) INTEGER array, dimension (NNB)
*          The values of the blocksize NB.
*
*  NXVAL   (input) INTEGER array, dimension (NNB)
*          The values of the crossover point NX.
*
*  THRESH  (input) REAL
*          The threshold value for the test ratios.  A result is
*          included in the output file if RESULT >= THRESH.  To have
*          every test ratio printed, use THRESH = 0.
*
*  TSTERR  (input) LOGICAL
*          Flag that indicates whether error exits are to be tested.
*
*  A       (workspace) REAL array, dimension (MMAX*NMAX)
*          where MMAX is the maximum value of M in MVAL and NMAX is the
*          maximum value of N in NVAL.
*
*  COPYA   (workspace) REAL array, dimension (MMAX*NMAX)
*
*  B       (workspace) REAL array, dimension (MMAX*NSMAX)
*          where MMAX is the maximum value of M in MVAL and NSMAX is the
*          maximum value of NRHS in NSVAL.
*
*  COPYB   (workspace) REAL array, dimension (MMAX*NSMAX)
*
*  C       (workspace) REAL array, dimension (MMAX*NSMAX)
*
*  S       (workspace) REAL array, dimension
*                      (min(MMAX,NMAX))
*
*  COPYS   (workspace) REAL array, dimension
*                      (min(MMAX,NMAX))
*
*  WORK    (workspace) REAL array,
*                      dimension (MMAX*NMAX + 4*NMAX + MMAX).
*
*  IWORK   (workspace) INTEGER array, dimension (15*NMAX)
*
*  NOUT    (input) INTEGER
*          The unit number for output.
